IMPROVEMENT IN WATERWHEELS.

Specification forming part of Letters Patent No. 143,040, datedSeptember 23, 1873; application tiled September 5, 1873.

To all whom it may concern:

Be it known that I, J osEPII TANEY, of Bangor, in the county ofPenobscot and State of Maine, have invented certain new and usefulImprovements in Water -Wheels and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which form part ofthis specification.

The nature of my invention relates to an improvement in water-wheels;and it consists in providing` the wheel with a spiral vent, above andbelow, at the outer rim, and a central discharge, so that the water willact upon it both by impact and pressure.

The accompanying drawings represent my invention.

a represents the scroll-casing in which the wheel is placed. Near theouter edge of both the top and bottom plates of this wheel are formedspiral vents c, placed eccentrically to the curve of the wheel, andwhich extend above and below the plates, giving vent to the water bothon top and bottom of the wheel, and which are about twice as long as thedepth of the wheel. The buckets e have their outer ends formed upon aradius of the wheel,

as shown at g, and then are curved inward toward the center at a tangentto the line of the wheel, leavin g the central vents t' between theirinner ends, which will discharge but onehalt' 'thevolume of the waterreceived by the wheel.

The water first acts upon the wheel by impact upon the buckets, andthen, as the water lls the wheel and its motion makes a pressure on therim of the wheel, the curved vents above and below in the rim give ventto this pressure, and free the wheel from Athe reaction of the water inthe scroll-passage, and thus becomes a pressure-wheel, the curves of thebuckets and the vents being such that both the impact and pressure ofthe water will be utilized to its full extent.

Having 'thus described my invention, I claim- A water-wheel having thecurved vents c in its outer rim, and the central vents t', substantially as herein shown and described.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 2d day of September, 1873.
